Parameters

path (String): The path of the file within the archive.

attributes (FileAttributes%): The returned attributes of the opened file, to be stored in the archive.

lastWriteTime (DateTime%): The returned last-modified time of the opened file, to be stored in the archive.

Remarks

This method opens a file using the following logic: If the Directory and the Files mapping are both null, the path is treated as relative to the current directory, and that file is opened.If the Directory is not null but the Files mapping is null, the path is treated as relative to that directory, and that file is opened.If the Directory is null but the Files mapping is not null, the path parameter is used as a key into the mapping, and the resulting value is the file path that is opened, relative to the current directory (or it may be an absolute path). If no mapping exists, the file is skipped.If both the Directory and the Files mapping are specified, the path parameter is used as a key into the mapping, and the resulting value is the file path that is opened, relative to the specified directory (or it may be an absolute path). If no mapping exists, the file is skipped.
